Hi!
Yet another LM75 temperature sensor. Add it to the list of
supported chips.
Changes since v1:
- disable "flowed" text messages in thunderbird, and hopefully get
clean patches this time (first patches sent since I got a new
computer) sorry about that *blush*
- add tag from Rob Herring
Cheers,
Peter
